An Examination and Validation of an Adapted Youth Experience Scale for University Sport     

Scott Rathwell  Bradley W. Young 《Measurement in physical education and exercise science》2016,20(4):208-219

Limited tools assess positive development through university sport. Such a tool was validated in this investigation using two independent samples of Canadian university athletes. In Study 1, 605 athletes completed 99 survey items drawn from the Youth Experience Scale (YES 2.0), and separate a priori measurement models were evaluated (i.e., 99 items, YES 2.0, YES for Sport [YES-S]). Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) results indicated issues with model fit. Post-hoc modifications improved fit, resulting in a 46-item, 9-factor model with five positive and four negative dimensions. In Study 2, 511 athletes completed the same items. The resultant model was confirmed using both CFA (comparative fit index [CFI] = .911, standardized root mean square residual [SRMR] = .056, root mean square error of approximation [RMSEA] = .040) and ESEM (CFI = .956, SRMR = .023, RMSEA = .034). The resultant University Sport Experience Survey provides a reliable and factorially valid instrument for measuring development in university sport.  相似文献

金圣叹的小说结构技巧论初探     

尹缉熙 《湖南第一师范学报》2004,4(3):82-83,88

金圣叹在评点《水浒传》时，着力探讨了长篇小说的结构技巧。首先，小说结构应是一个有机的整体；其次，小说结构应具有形式美。我们对此进行了较详细的探讨，这对建构具有民族特色的小说美学，对当今的长篇小说创作都是十分有益的。  相似文献   

Explaining the substantial inter-domain and over-time correlations in student achievement: the importance of stable student attributes     

Gary N. Marks 《Educational Research and Evaluation》2016,22(1-2):45-64

Multi-domain and longitudinal studies of student achievement routinely find moderate to strong correlations across achievement domains and even stronger within-domain correlations over time. The purpose of this study is to examine the sources of these patterns analysing student achievement in 5 domains across Years 3, 5 and 7. The analysis is of longitudinal population data of over 22,000 students and utilizes fixed-effects models to incorporate stable general and domain-specific latent factors. These latent factors correspond to a general cognitive-ability-like factor and specific aptitudes in particular, or types of, subject areas. The preferred model incorporates both general and domain-specific latent factors with stronger effects for the general factor, although the domain-specific factors are particularly strong for spelling and numeracy. When taking into account general and domain-specific latent factors, the effects of student’s socioeconomic status (SES) and school SES are trivial.  相似文献
